ULSD rant

[Highbeam]

Great post newblue, see, that junk can be removed. Unfortunately very illegal (federal laws) and pretty easy to get caught.

It's not the ULSD causing problems described by the OP. It is the EPA's mandated pollution control. I run ULSD in my 2000 powerstroke and have no problems with a DPF or regen.

So where are they selling all the trucks they're getting rid of prey tell?????

Some studies have shown that regulations force change faster than waiting for voluntary compliance.

In the 60s cars had no emissions controls and ran fine.
In the 70s emission controls were mandated and the cars ran like poo.
In the 80s mfgs had given up on kludges like EGR and had switched to DME and electronic fuel injection. result: cars ran great, got better fuel economy, and produced fewer emissions and are way more reliable. They are also more expensive, naturally.

The manufacturers whined and complained and said it couldn't be done (CAFE plus clean air standards) but they did it when they were forced.

I'm not advocating bad-running diesels (although the new 2011 F350 runs GREAT) but I'm not in favor of air pollution either. I'm just saying in the long run sometimes these kind of problems lead to improvements.

The last round of diesel emission laws for light duty pickups was/is a complete failure. I have an 06 model diesel pickup that gets a consistent 18-21 mpg, hand calculated. Take the current offerings by the big three and unless you remove the emissions equipment none of them are capable of making the same fuel economy numbers. The trucks aren't capable of doing more work, so where is the advantage of LESS fuel economy?

While this was true for the 2007.5 though 2010 the 2011's from Ford and GM are doing much better with the DEF. From the reports I have seen on the new Ford its averaging about 18mpg.

let me clear up a couple things

1) I started talking about pickups. The fleet leases they have. And no one wants anything to do with these trucks when they are done. Arctic cold in the winter and sea breezes all summer (salt)

2) Being able to plug in is not enough, by the time the engine and the cab warm the DPF is crunched. And the speed limit on the field is 35 MPH. So no high speed runs to clean the filter

3) The problems are not just on the pick ups. The truck drivers getting new rigs are having fits. losing time due to complications and break downs. Most of the older trucks are going to stay on the road a long time

4) As for the delay on the regeneration, please remember that it can take 6 hours to get over the pass, how long can you delay it? Trust me, the haul road to the north slope is the worst in america. steep grades and brutal weather.

5) UREA does freeze, or at least gells to the point it won't work. Of coarse it was 58 below.

The systems on the trucks are not very usable.

Sad but I had to spend another $1500 to overcome these issues on my truck. EGR and DPF delete and my mileage went from 13 to 19. Another bad thing is that it's not legal to do this in all states.

It is not legal to do it in ANY state. It is a federal violation, which you just documented for all the world to see

All the emissions junk on new trucks will keep me driving my 96 Powerstroke until the wheels fall off, then I'll fix that and keep going...:thumbsup:

I totally agree, and anybody who Quotes "lucky Jack Aubry," must know what he is talking about.

Show me the emissions laws that pertain to the dpf and egr removal. The only one I know of is that the cat has to stay and I didn't say anything about removing that. I'm not trying to be a butt head just uninformed. I can also tell you that EGR on a diesel is a bad thing. Pumping soot and exhaust gases back into the intake is a good way to kill a diesel.

Edit: This pertains to pre-2010 engines

I salute you for doing that, I'm thinking about it myself. Mine is a chassis truck so no cat (I think). Some I read about on the diesel forums said no great increase in mpg, but a much nicer running truck, more power, better sound etc.

But in my case I don't see an imediate need.

I have the first 07 6.7 CTD that required ULSD. I'm getting the same milage with this truck as I did with my 95 Cummins powered Dodge, and this truck weighs 3,000 pounds more and has almost 2 times the HP as the 95. It is no MPG to brag about but what can I complain about either.

The North slope probably should have seperate standards or waivers to keep those machines running in extreme conditions.
